"You are quite sure," Smithy asked, "that you know absolutely nothing about this boy's past? His parents, his birthplace--anything at all? There must be some clue."

"You know very well I don't," Possy retorted angrily.

"I just thought that perhaps you might have subjected him to hypno-research," Smithy said, placatingly.

"I wouldn't dream of such a thing--" Possy began--and stopped with a gasp. "How did you know about that?" he demanded.

Smithy was flustered. "I--well, that is--" He could think of no convincing answer. Hypno-research was one of Possy's most secret projects. He had used it constantly in his efforts to determine reasons for non-conformity to set patterns of behavior in some of his more recalcitrant students. He had kept it a secret because it added up to an admission that perhaps heredity could play a part in the development of a student's character.
